The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

This paper examines the use of options contracts by firms acquiring rights to commercialize university technologies. By combining information about the sequence of licensing decisions with characteristics of the firms and technologies involved, I explore factors that shape decisions to purchase and exercise option contracts for these technologies. Decisions by firms that considered but did not purchase an option or a license are included in the sample. Consistent with the basic premise of real-options theory, I find that firms are more likely to purchase option contracts for more uncertain technologies. Also in line with theoretical predictions, I find that firms that are better able to evaluate an external technology are less likely to purchase options before licensing. The results also highlight more complex motives for exercising options in technology licensing. On the one hand, firms appear to benefit from their ability to learn about the technology during the option period. On the other hand, firms that are better able to "absorb" the technology during the contract period may have reduced incentives to subsequently license the invention.
